osgearth投影坐标转WGS84坐标出错

wangyitao

本人用osgEarth::SpatialReference::get方法定义epsg为4544的投影坐标系，想要转为WGS84坐标系，结果出问题了，希望大佬们不吝赐教，代码如下：


osgEarth::SpatialReference* utm =
        //osgEarth::SpatialReference::get("epsg::4544");
        osgEarth::SpatialReference::get("+proj=merc +epsg=4544 +units=m +no_defs");

osg::Vec3d outpoint;
osgEarth::GeoPoint wgspoint;

if(utm->isGeographic())
{
    qDebug()<<"IS GEOGRAPHIC"<<endl;
}
else if(utm->isProjected())
{
    qDebug()<<"IS PROJECTED"<<endl;

    osg::Vec3d outXYZ(info.x, info.y, 0);
    osgEarth::GeoPoint utmpoint(utm, outXYZ, osgEarth::AltitudeMode::ALTMODE_ABSOLUTE);
    wgspoint = utmpoint.transform(s_mapNode->getMapSRS());
}
outpoint = wgspoint.vec3d();

double _x;
double _y;
double _z;
_x=outpoint.x();
_y=outpoint.y();
_z=info.z;
